Question

Soha deposited rs 5200 in her account . She gave notes of denomination of rs 10, 50, 100 in the ratio 2:4:3 respectively . Find the number of notes in each denomination

Answer 1

$1050100 \times 2 \div 9 = 233355.5 \\ 1050100 \times 4 \div 9 = 466711.11111118 \\ 1050100 \times 3 \div 9 = 350033.33333$

Answer 2

Let 10 rs note= 2x

Let 50 rs note=4x

Let 100 rs note= 3x

10(2x)+ 50(4x) +100(3x)=5200

20x+200x+300x=5200

520x=5200

x=5200/520=10

So,she has 10 rs note=2*10=20

50rs note=4*10=40

100rs note=3*10=30
